Method and apparatus for deploying virtualised network function

In a method of deploying a virtualised network function (VNF), a virtual network function manager (VNFM) obtains a virtualized network function descriptor (VNFD) that includes a primary file and one or more secondary files that have a mapping relationship with the primary file. The primary file includes a deployment parameter of each secondary file, and a association relationship indicating that a value of a flavour parameter of the VNF is associated with the deployment parameter of the secondary file. The VNFM then determines a target file from the one or more secondary files based on the value of the flavour parameter of the VNF and deploy S the VNF based on the association relationship and a mapping relationship between the primary file and the target file.
